'BESILIENT To all whom imag/concern: t

Be it known that we, WILLIAM A. BUCK- NAM, of Truckee, in the county ofNevada .resilient wheels.

and State of California, and WILLIAM STICKEL', `of Greenwood, in thecounty of Eldorado and State of California, citizens -of the UnitedStates, have invented new and usefullmprovements in Resilient Wheels, ofwhich the following is a` specification.

Our invention relates to improvements in ible by compression of thetread members as they pass beneath the wheel in contact with the'ground. i

It also comprises details of construction which will be more fullyexplained by ref erence to the accompanying drawings, in which- Figure 1is a fragment of a wheel, showing i an exterior view of the tread andcasings.

Fig. 2 is a vertical sectiony of a portion of the rim of the wheeltransverse to the aXis, the wheel in this instance being provided witha. dust proof ring, as shown. Fig. 3 is a perspective view of a casingand its y tread member. Fig. 4 is a transverse section of the same,showing the inclosed spring.

Fig. 5 is a detached view of one of the fillers.

A represents a wheel, having a hub, spokes and felly of any'usual orsuitable construc`- i tion and-surrounded by avrim 3, which, in thepresent case, is shown as channeled in transverse section, with the openportion outward. This rim serves to receive and guide the hollow casings2. These casings are preferably made rectangular and carry,

upon their outer closed periphery, sections 7 of the tread. Thesesections are fixed to and movable with the casings2 and may be made ofrubber or metal." In' the present case they are shown with beveled orinclined ends overlapping each other v'likethe scales of a when inplace, forminge continu Specicationvof Letters Patent.

strength to support the weight of the car-v riage. The innerends ofthese springs rest within the bottom of the channeled rim 3 where theyare suitably maintained in position. The outer ends of the springs abutagainst the interior of the casings 2, to whichv they may be secured, ifdesired. A

series of these casings'is spaced apart a short distance and extendentirely laround the wheel, with their sectional shoes overlapping eachother to form a complete tread.

In order to maintain these in the proper position and make themsubstantially rigid, circumferentially, we have shown the inner edgesofeach casing as turned outwardly, forming flanges, as at 2a. Theseflanges engage with similar flanges 6 which are formed upon thewedge-shaped filler pieces. The taper of the sides of these fillers issuch that they form parallel channels between them in which therectangular casings 2 are freely slidable under compression of thecontained springs. The flanges 6 abutagainst the sides of therectangular casings 2 and thus prevent their moving in the direction ofthe circumference of the wheel, while the channeled rim 3 retains themin position transversely and the taper of the fillers 5 forms the properrectangular-shaped spaces for the reciprocationof the casings 2.

Having thus described our invention, what we claim and desire to secureby Letters Patent is'- 1. The combination with a-wheel having achanneled rim, cfa circumferential series of casings independently'slidable in the channel of the rim, resilient means supportingthecasings for independent movement, and a tread shoe carried by leachcasmg in abutting relation with the adjacent shoes to form a continuoustread, the abutting ends of ythe shoes being beveled and one end beingprovided with a tongue extending entirely across the same While theother end is provided` With a groove to receive the'tongue and thus lockthe abutting shoes'in alinement. l

2. The combination with a Wheel having a channeled rim, of rectangularinterspaced vhollow oasings closed at their outer ends and fittingbetween the sides of thel rim, the inner edges of the casings beingprovlded with ianges turned Aoutwardly toward the adjacent casings, aspiral spring for cach casing having its inner end resting in thechannel and its outer end extending 'Within and resting on the closedouter end of the casing, v"Wedge-shaped iilling blocks secured tothe rimsides and forming guide spaces Within Whichthe casings are slidable, the

outer portionof each filling block being provided With oppositelyprojecting flanges overlying the flanges of the adjacent casings, and atread shoe carried by each casingand abutting the adjacent tread shoeswith the abutting ends lying in overlapping relation', one of theabutting ends of. adjacent shoes being formed with a tongue extendingacross the end and the other und being forr'ned with a groove normallyreceiving the tongue.
